Bit-Tech published a review of the Asus P5Q Deluxe* motherboard, based on Intel's P45 Express chipset.

A quote from the article:

Asus has appealed to the budget conscious, feature loving, overclocking enthusiast very well indeed even though some of these features are mutually exclusive in use. It's not perfect but it's evidently a clear that this is a thorough evolution over previous Asus products, even previous P35 boards as a whole. It's raised the bar //massively for what mainstream should be compared to the previous generation, yet in almost every area it's still left us wanting more. Its hardware features are innovative and daring, but we find ourselves rhetorically questioning //"would I actually use it though?" If yes, then jump on it like it was made of gold. Asus has proved that its P45 P5Q Deluxe is a step up from P35, and almost emulates X48 but for far less money: it has our vote for this reason alone.
